Utrophin-GFP and α-Tubulin-mCherry in dividing Skittles-depleted S2 cells as shown in Fig. 2 C. Dividing Skittles dsRNA-depleted cell stably expressing Utrophin-GFP (GFP-UtrCH; black, left; green, right) and α-Tubulin-mCherry (red, right). Images were analyzed by time-lapse microscopy using a microscope (DeltaVision). Frames (focal planes) were collected every 7.5 s. Time compression is 37.5.
